ablev wirerod S23-1- mountedVV in sleeves Q3, and at the opposite side of thebase y10 IY Vprovide arlo'clr for securing the bottom Vlil in closed position;V this lock consisting of Va, slid- Y n on the bottom 14 so as to secure said bottom in closed position, said rod and sleeve being familiar features in this art. rlhe main body of the bottom 14 is offset upwardly, as shown-in Fig. 1, and this portion of the bottom 14 is perforated, and within the recess formed in the lower side of said bottom 1 mount, on a pivot 27, a rotatable disk 23 having air inlet openings 29, 30, which may be brought more or less into register with the openings 31 provided in the bottom 14 for the ingress of air. The disk 28 provides a means for regulating the draft up through the bottom of the base 10, since the openings V29, 30 therein will be brought into more or less register with the openings 31, as occasion may require, the air inlet to the base 10 being reduced on occasions when there is a strong breeze. The bottom 14 may be provided with feet 32 for supporting the lantern upon a base without closing the air linlets through the bottom 14. The base 10 at one side is equipped with a sliding door 33 (Fig. 5) which lies against the inner side wall of the base and is guided in channels formed by horizontal flanges 34 in an ordinary manner, said flanges affording runways and said door being equipped with a small knob 35 for convenience in operating it. The door 33 atone edge is provided with a notch 36 adapted to pass upon a wick-operating shaft 37 asl shown. The vwick-operating shaft 37 extends to the exterior of the base 10 and is provided with an operating wheel 38, and by reason of the fact that the shaft 37 does extend outwardly beyond the side of the base 10, 1 provide said side with a vertical slot 39, as indicated by dotted lines in Fig. and with a branch slot 40 which is horizontal and leads laterally from the upper end of the slot and merges into a short vertical slot or recess 41 which finally affords a seat and lock for the shaft 37.

The lamp is to be inserted upwardly through the bottoni of the base 10 when the bottom 14 thereof is opened, and during this insertion of the lamp into the lantern the door 33 will be caused to uncover the slot 39 and permit the shaft 37 to be passed upwardly through said slot and then, on the turning' of the lamp, carried along the branch slot 40 and finally be allowed Yto seat in the recess 41. After the lamp has been introduced to its position the door 33 will be slid toward the shaft 37 and close off the slot 39, as shown in Fig. 5, thereby excluding the passage of air through said slot as well as through the branch slot 40 and recess 41. ln

the absence of the door 33 considerable air' mi ght pass through the slots 39, 40 and recess 41,A said slots then being open. 1 locate the raised or lowered without opening the lantern or removing the lamp therefrom.

The lamp comprises an oil-fount 42, an up` 46. The oil may be poured into the fount 42 through an inlet 47 of ordinary construction. The wick will be raised and lowered by means of the usual wick-wheelssecured on a transverse shaft 43 having on its outer end a sprocket-wheel 49 connected by a chain 50 with a sprocket-wheel 51. on the aforesaid shaft 37. through a chamber afforded by a sleeve 52 which is offset inwardly from the outer wall of the neck 43, in which position said chain 50 will not interfere with the application of the lamp to the sleeve 17. The chain 50 is confined at the inner side of the sleeve 17, and the sleeve 52 being integral with or secured to the neck 43 will not permit leakage about the inner end of the shaft 37. The chain 50 permits of the operation Vof the wick-wheels on the shaft 43 from a point below the lens 12 and exterior to the base 10, and this is a feature 1 desire to accomplish since by reason thereof the wick 44 may be adjusted without opening the bottom of the lantern Aor removing the lamp.

The neck 43 is provided on its opposite sides with pins or small knobs 53, which are utilized in connection with the grooves 18 in securing the lamp in suspended' position within the neck 17. kIn applying the lamp to position in the lantern the bottom 14 is opened downwardly and the door or shutter 33 is slid from over the slot 39 in the side of the base 10, and thereupon the lamp may be inserted upwardly into the lower end of the lantern, the shaft 37 being moved upwardly through the slot 39 and the knobs 53 on the neck 43 caused to pass upwardly through the grooves 18. lVhen the shaft 37 has reached the upper end of the slot 39 and the knobs or pins 53 have reached the upper end of( the vertical portions 19 of the grooves 18, the lamp will be turned angularly so that the shaft '37 may move along the branch groove 4() and finally reach its seat in the recess 41 and so that the knobs or pins 53 may, at the saine time, travel along the grooves 20 and become seated in the recesses 21, in*l which position of the lamp said lamp be comes securely suspended within the sleeve 17, and the recesses 21,0fthe grooves 18 and 41 of the slots 39 securely hold the lamp against angular orY twisting movement.

rllhe chain 50 extends vertically After the lamp has been introduced into the lantern and becomes properly positioned therein, the door or shutter 33 will be moved to its closed position, covering the slot 39, as shown in Fig. 5,- and the bottom 14 of the lantern will be closed and' locked in its closed position.

The lens 12 is a tubular Fresnel lens, and said lens requires no particular description,

except to say that itis in one piece and tubular and removable, when required, from the lantern, said lens not beingV a'xture rigidly 4secured within the lantern parts.

The lens 12 may, therefore, be readily cleaned whenever required land replaced by new lenses, whenever that shouldI beneces'- sary. In the usual type of lanterns the lens is rigidly fastened in place vand not removable except Awith vconsiderable ditticulty, it not being intended that the lens maybe yremovable. The upper andllower ends of the lens l2 are formed with smooth annularzsec tions 54, 55, respectively, the sectionrf55removably fitting within the channel 22, and.

the section 54 being within a reasonably closeffitting opening 56 in a locking ring 57,

partY of the superstructure of which forms a the lantern.

The superstructure 11 comprisesa domedVV sheet-'metal top 58 having a central' upwardly extending tubular chimney portion 59, a base ring 60 to which the topt58 is secured by a hinge 6l, the aforesaid looking ring 57 which is supported by said base ring 60, aneXterior bell-shaped protector or hood 62 which upper end of the sleeve 6dV is correspond' ingly perforated, as at 67, and said sleeve is made rotatable so as to actas a register'for cutting off more or less ofthe area ofthe perforations 66, as occasion may require. I

secure aY handle 68, to the sleeve 63 as a con;` venience for rotating saidsleeve. Thever tical sides of the. hood 62 arespaced outwardly from the sleeveV 63Iso-as to createa commodious passage vfor the escape of the products of" combustion and maintain a proper draft through the lantern, and to prevent a strong breeze A.or sudden gustofl wind from interfering Vwith'the correct action of the lantern,I provide the baffleplates 64, 65 in thespace between the hood 62y and sleeve 63.,V the baiiieiplate 64extending inA `l wardly from the hood. butnottouching ythe Sleeve'63, and the bafflejplate'.65.*eXtending outwardly from the chimney' 59 toward but discharge ofthe heated airand 'products of combustion fromthe `chimney 59 and also bajli'le anyT wind orbreezewhichmight, es-

Y The domed top` 58Y is secured'at onervedge by 6'5" the "hinge Glfto'the'base rin'g'GQ, and hence saidtop maybe turned upwardlyfrom overf the lens l2 whenever necessary. I secure' the top 58 in its closed position bymeans of aV suitablei locking wire f which may be wire 7 Oris slid in the-oppostieY direction, the wire will lock theVv top 58 in its closed posi-- tion, ak locking wire 7 Ofof a character illus'- trated being familiar in this art.

' The base-ring 60 is' a fiat ring of substanl tial strength andv supported lupon-the upper ends of the'cage'wiresvwhoseupper endsv are fastenedlto the ringGOYa-nd whoselowe'r ends' are secured tothe top l5 ofthe ybase 10. The ring 60 is-'formed in .its `upper surface Vwith an annularf depression `orrecess 74 into which is seated the locking ring 57, said ring 57 being, atY its inner edges, extended inwardly'beyond thefinner edges ofthe rin 60, as shown iii-Figi; l-,so that the ring'57.v may ratherl snugly'engage the upper plain section 554 ofthe Vlens 12,said ring 57 being A i provided for4 the purpose of'holdingV the upper end of the lens l2 stationaryfand more especiallyagainstvibration.V Ther ring 57 is a flatjband of sheet metal and 'has at certain points in its outer'edg'e recesses 7 5,-a-s shown` in Fig, 3and thesefrecesess are utilized i connection with small 'plates 76jsecured totY the ring 60v for locking the ring 57 in osi-q`V tion."

iso f .Y tern, the topll" then beinginits open vposi-YV 1 inbei'ore described, and it is believed that further description of the structural features may not be required. The operation of the lantern will also be understood from the foregoing description. The lantern is constructed of parts which may be readily manufactured and assembled, and the lantern is efficient in use. rlhe drafts through the lantern for the support of combustion may be controlled at will, and means are provided at the upper end of the lantern for excluding strong breezes and gusts of wind. The interior of the lantern may be readily gotten at, since the bottom 14 and top 58 are hinged to their respective supports, and the lens 12 may be removed and replaced at will. The lamp becomes securely'fastened in position and the wick 44 may be adjusted from the outside of the lantern. The form of the base. l0 and oil-fount 42 permit the lantern to be supplied with an adequate quantity of oil.
